Application filed September 18, 19 18. Serial No. 254,588.

To all whom it may concern:

Be it known that I, Emms'r HENRY Jonas, :1 subject of the King of Great Britain, residing at 4 Grange road, Canonbury, London, England, have invented new and useful Improvements in Welding and Brazing, of which the following is a specification.

This invention relates to welding and brazing-rods which are used with an oxyactylene or other blow ipe and has for its I object improvements w ereby the weld or joint may be effected with greater celerity' and efliciency than heretofore.

According to this invention, the welding rod is constructed or composed of all-the materials necessary to produce under the heat of the blow pipe the requisite metal or alloy for the purpose intended.

With this object a metal base, such as mild steel or cast iron, or brass or gunmetal in the form of a rod, tube, or channel, is

electroplated with and has secured thereinanother metal or a combirfia'tion of other metals or alloys so that thewelding rod under the influence of the heat of the blow pipe deposits the required metal or alloy to suit the weld or joint. In the case of steel or iron the surface of the rod or the tube may be casehardened to provide an additional amount of carbon.

For example, a mild steel rod which has been electroplated with nickel when used as a welding rod produces a metal weld or joint of a greater tensile strength than if a and has the further advantage that the molten metal flows more freely and settles with greater density than does nickel steel under similar conditions.

Again: all the materials necessary for the aluminium, or the like may be employed for depositing metal on the cutting parts of one or more metals or alloys may be secured in the base in accordance with this invention.

Figures 1 and 2 illustrate a channel sectlon base 11 containing a strip 6 of a metal or alloy, Fig. 2 representing the rod after it has been subjected to pressure in order to se ure the .strip in position.

Figs. 3 and 4 illustrate a channel section base a containing a, wire b of a metal or alloy and a filling c of more or less rare metals in powder or paste form, Fig. 4 re resenting the rodafter it has been su jected to pressure to secure the contents.

Fig. 51llustrates a wire or ribbon base (1 wound (in close or open spirals) upon a wire 6 of a metal or alloy.

It is advantageous to inclose the metal or alloy within the base, as illustrated by way of example in the accompanying drawings, as, by so doing the metal oral 0y is protected and does not burn away uselessly. These remarks, however, do not apply to eleztro-plated rods which I find quite satisfactory.

I claim formed of a basic metal, an alloy and a welding mixture secured within said mom-- ni kel steel welding rod had been employed, be

r. 2. A solder formed of an allo a welding mixture, and a member forme of a basic metal bent to inclose and secure the alloy and weldin mixture within the member.

3. A sol or formed of an allo'y, and a basic metal member wound around said alloy in the form of a coil. y

In testimony whereof I have signed my name to this specification.

ERNEST HENRY JONES.
